NIGHT VISION AND EYESIGHT

March 24th 2009 -

Beta-carotene is the natural yellow colouring found in vegetables. It was in the news during the Second World War when it was said that pilots in the British Airforce were fed carrots as a source of nutrient to improve their night vision. Many people believed that this was how they could spot the invading bombers but the truth was that the British had invented radar first which the Germans had not as yet discovered.

Recent evidence does show that beta-carotene and vitamin A are very important nutrients for the production of visual purple and this visual purple in our eyes is needed for night vision. Therefore, a diet rich in foods containing beta-carotene and vitamin A is required for us to have normal night vision. Without these nutrients we are unable to re-manufacture our visual purple after it has been damaged. Some of the things that can damage visual purple and reduce night vision are television screens, VDU screens, and bright lights.

Blueberry helps improve night vision. Taking the extract of the herb also restores visual acuity after exposure to bright light (glare) and can improve vision in low light.

We should be looking at a natural supplement of beta-carotene if we are not getting enough in our diets from leafy green and yellow vegetables. Beta-carotene is also an antioxidant. (For more information on antioxidants, refer to antioxidants in this book.)
